Good day Sifu,
My friend's notebook screen got marker pen drawing by his nephew, seeking for advice in case you have handled this before ?

he tried using water to clean up, the ink mark was gone, but the strain still there

Thanks

try rubbing alcohol

Got a few method, try using minyak angin, it can wipe out most chemical.

If not working, can try solution mixture of bakingsoda + vinegar. Not spray it on top but just dip and wipe.

use whiteboard marker also can. write on the permanent marker and quickly wipe it off. if not any alcohol can do.

whatever chemical u use. pls try a bit on corner before destroying the screen and the coating

some advice on not to use alcohol as it could damage the screen
